ABSTRACT:
A waveguide horn antenna includes a horn-shaped body portion and one or more feed structures. Each feed structure includes feed locations positioned between spaced apart ends of the body portion according to short circuit locations of desired frequencies to facilitate propagation of electromagnetic energy at the desired frequencies. Multiple frequency bands can be supported with the antenna by employing more than one axially spaced apart feed structures having associated feed locations arranged along the body portion of the antenna.
